lNGOT-YCASTING YMACHINE.

SPECIFICATION formingpart of Letters Patent No. 594,157, dated November23, 1897. Application filed February 24, 1897. Serial No. 624,853,l (Nomodel.)

To a/ZZ whom t may concern:

Be it known that I, JOHN ILLrNGwoRTH, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Ingot Casting Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference- Inarkedthereon, which forma part of this specification.

' The objects of this invention are to reduce the cost of castingingots, to facilitate the operation of casting and enable saidoperations to be accomplished with less labor, to effectively preventthe formation of the defects known as piping due to the shrinkage of themetal after the outer sides of the ingot have set and hardened, andto'secure other advantages and results, some of which will be referredto hereinafter in connection with the description of the working parts.

While the invention is adapted for the production of ingots of allsizes, I employ it more especially in the manufacture of ingots of alarge size.

The invention consists in the improved ingot-machine and in thearrangements and combinations of parts thereof, all substantially aswill be hereinafter set forth, and nally embraced in the clauses of theclaim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each vot' the views, Figure lis a side elevation of the improved ma- Fig. 2 is a plan of the same.Fig. 3 is a vertical section taken on line @c 0c, Fig. l. Fig. l is aperspective view of a certain mold carriage or truck. Fig. 5 is a sideview and plan of a certain wedge employed in connection with the ingot.Fig. 6 is a planshowing two trucks or carriages coupled, and Fig. 7shows a back-to-back pair of mold-sections not integrally joined. Fig. 8is a vertical section taken centrally through the series of molds andcoperating parts.

In said drawings, a indicates the bed-plate, upon which the severalparts are supported.

This is provided at a suitable central point with `a heavy verticalstandard b, at opposite sides of which are series of molds c, arrangedin separable sections. Beneath said moldsections and on said bed-plateare tracks or ways d d, on which are arranged cars or trucks e c ofabout the length and width of a pair of mold-sections placed back toback, as shown in detail in Fig. 7. Said mold-sections placed back toback may be in united pairs, as in said Fig. 7, or they may beintegrally connected, as indicated in Fig. 2, the latter constructionbeing preferred. To the central standard, at opposite ends andadjacentto said ways, are fastened mold-sections c' c', their backs lyingagainst the vertical sides of the standard and bolts being preferablyused in fastening them in place. The fronts or working faces of saidsections c are grooved or chambered longitudinally in correspondencewith the working face of the next moldsection c in the series, thechambers of the two sections uniting to form the first moldchamber ofthe series.

Next to the second vertical mold-sections c, with their backs thereto,are third moldsections 0. These form pairs with said secondmold-sections and may be integral therewith. Said pairs of mold-sectionsc c" are carried by the first carriages or trucks e of the series, saidtrucks being of substantially the same size in plan as said pairs ofmoldsections. Said carriages or trucks are provided at their oppositeends with coupling means, whereby the several carriages of a series maybe coupled together in a train, the couplings preferred at the presenttime being shown in the detail plan of the said trucks, Fig. 6.

f Following the pairs of mold-sections c 0 are other pairs c c c6 c7,and at the opposite ends of the series are other singlesections e8,which are fastened to vertical compressionbeams f, to which the pistonsg g of the hydraulic presses 7?. are connected.

The pressure of the pistons g upon the beams f forces said beams againstthe series of mold-sections, compressing said sections against oneanother and against the central standard, so that the mold chambers areclosed to receive the molten metal.

IOO

j The mold-sections are held in horizontal line by metal moldguides t' ion opposite sides of said sections, which guides press against saidmold-sections to hold them in position. They allow, however, themovements back and forth of the molds on the trucks e under theinfluence of the hydraulic devices when the said trucks are coupledtogether. Said trucks are conveniently nncoupled from the side bywithdrawing the coupling-pins j.

The trucks e work upon rollers 0, placed between the ways CZ d, saidtrucks being provided with depending stop projections p, which preventthe displacement of said rollers with respect to the trucks.

Then the back-to-back pairs of mold-sections are in separate pieces,said sections are coupled together by pins 7a. (Shown in Fig. 7.) Theseare of course dispensed with when the pairs are integrally connected.The metal mold-guides t' 1l may serve either alone or in connection withother parts as platforms upon which the operators may work. They arepreferably supported by connecting-bars ZZ, joining the central standardb with the hydraulic cylinders 7L, which connecting-bars thus serve adouble purpose in holding said guides and in maintaining the cylindersand standards in fixed relation when pressure is brought to bear.

The molds preferably are arranged in two series independent of oneanother, so that said series may he worked alternately in the castingoperations, as hereinafter described.

Vedges m are employed in compressing the ingot to close the pipe. IVprefer to provide a separate Wedge for each mold-chamber.

In operating the device, the trains of carriages or trucks being coupledtogether and the mold-chambers being closed under the pressure of thehydraulic pistons g, the first mold-chambers r, or the ones nearest thecentral standards, are one after the other filled with molten metal.After the second of these is filled the first cast ingot will be abouthardened sufficiently to sustain its weight, after which itsmold-sections are separated by means of the hydraulic piston drawingback the train of carriages and moldsections thereon from themold-section fast to the standard. A wedge on is then forced between theingot and the inside wall of the mold,-

and the hydraulic pistons are again operated to close the mold-sectionsc c together, so that the now viscid or comparatively soft metal of theingot center is compressed from the outside sufficient to compensatefurthe shrinkage, and the pipe opening or central defeet is prevented.This being accomplished, the first mold on the opposite side of thestandard is in like manner opened, another wedge inserted, and the moldagain closed to effect the same result. Vhile this closing operation ofthe second chamber fr is going on, one of the second mold-chambers s isbeing filled with metal and the first pair of backto-back sections c" eis uncoupled from the train-section 0", so that the chamber r willremain closed While the ingot therein is cooling. WVhile this thirdingot is cooling, the second chamber s is iilled, the preliminaryoperations with reference to its chamber r being completed. The firstchamber s is then opened, its wedge inserted, and again closed by thepressure of the hydraulic piston. These alternate operations arecontinued in connection with the remaining molds of the train until thechambers t t and u 'a are filled with metal and all are compressed.

The molds of a train may be varied in number and shape at will or asconvenience rcquires. The carriage may be dispensed with and the moldsmay then slide on the ways or between the same; but I prefer thearrangement iirst described.

Having thus described the invention, ,what I claim as new isl. Theimproved ingot-machine herein described comprising a central standard, aseries of separable mold-sections arranged in back-to-back pairs onopposite sides of said central standard, carriages or trucks, eachsupporting a back-toback pair of said moldsections, coupling means forthe carriages, and means for compressing the in got between saidmold-sections, substantially as set forth.

2. The improved ingot-molding machine herein described comprising aseries of molds each comprising two separable sections, the said seriesof molds being arranged upon a series of carriages, the contiguoushalf-sections of adjacent molds being arranged back to back on eachcarriage whereby when the carriages are uncoupled, the molds can beseparated, wedges adapted to be inserted within the 1noldchamber, afterthe sections thereof are separated and means for coinpressing themold-section s, after the insertion of the Wedges, and means forcoupling the carriages, substantially as set forth.

3. The combination with a central standard, of horizontal ways el, forcarriages, said carriages e, vertical mold-sections, stationed upon saidcarriages, the two sections of each mold being arranged on differentadjacent carriages of the series, hydraulic compression devices,stationed at the ends of the series, wedges adapted to be forced intothe molds after the partial consolidation of the in got and theseparation of the mold-sections, and means for coupling the carriages,substantially as set forth.

Il. The combination with a series of sectional molds, of a series ofcarriages supporting said molds, each carriage supporting a pair ofsections of adjacent molds, the said sections being back to back, andcoupling means suitably disposed to hold the said sections in train,substantially as set forth.

The Combination With vertical horizontally-movable molds, arranged insections, of a series of carriages adapted to be coupled together, eachcarriage having depending stop projections, 10, adapted to limit themovements of the rolls beneath said carriages and said rolls arrangedbetween the said stop projections, substantially as set forth.

7. The combination With a track or Way and a series of separablecarriages thereon, of compression means stationed at opposite ends ofsaid track or Way, a series of mold-sections, all separable Vfrom oneanother to permit them to be opened apart from one another and couplingmeans constructed and arranged to hold a part of the sections closedWhile others of the series are being drawn zo apart, substantially assetforth.
